[0002] Chinese utility model patent CN217252274U discloses a punch press for steel structure production, including a support frame. A support box is fixedly installed on the upper outer surface of the support frame, and a receiving assembly is movably installed inside the support box. A stamping clamping assembly is detachably installed in the middle of the upper outer surface of the support box. This utility model's punch press for steel structure production, through the set stamping clamping assembly, allows the steel structure to be clamped in position during the stamping process by the pneumatic stamping mechanism, preventing the steel structure from shifting and thus improving the stamping accuracy of the steel structure. However, the aforementioned patent has the following drawbacks: it lacks a protective structure, and steel chips generated during stamping will splash into the surrounding processing environment, contaminating the processing environment and equipment. Utility Model Content

[0003] The purpose of this utility model is to provide a punch press for steel structure production with a protective structure, so as to solve the problems mentioned in the background art, such as the lack of a protective structure in existing punch presses for steel structure production.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A punch press for steel structure production with a protective structure includes a worktable, a punch head mounted on the top of the worktable, a telescopic protective cover between the worktable and the mounting frame, the telescopic protective cover being fixed to a mounting plate, the mounting plate being connected to the mounting frame by a spring, and a pressure rod mounted on the drive cylinder of the punch head, the end of the pressure rod being positioned above the mounting plate.

[0006] The telescopic protective cover includes a first cover and a second cover, which are slidably fitted together.

[0007] The bottom of the first cover is located in the limiting groove inside the second cover. The bottom of the second cover is provided with a limiting block, and the top of the second cover is provided with a limiting plate. The limiting plate is provided with a sliding groove, and the side wall of the first cover slides in conjunction with the sliding groove.

[0008] There are two sets of springs, one on each side of the mounting plate.

[0009] The mounting plate has a machining groove in the middle, which is located directly below the stamping head.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] In this invention, the workpiece can be stamped by moving the stamping head, and the telescopic protective cover can be moved to protect the workpiece from the surrounding area, thus effectively protecting the processing environment. Attached Figure Description

[0013] Figure 2 This is a front view of the present utility model;

[0014] Figure 3 Schematic diagram of the telescopic protective cover structure of this utility model.

[0015] In the above attached figures, the worktable is 1, the stamping head is 2, the mounting bracket is 3, the telescopic protective cover is 4, the pressure rod is 5, the spring is 6, the first cover is 4-1, the second cover is 4-2, the limiting groove is 4-3, the limiting block is 4-4, the limiting plate is 4-5, the slide is 4-6, the mounting plate is 7, and the processing groove is 7-1. Detailed Implementation

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figure 1-3 As shown, the punch press for steel structure production with protective structure provided by this utility model includes a worktable 1, a punch head 2 arranged above the worktable 1, the punch head 2 being mounted on a mounting frame 3, and the punch head 2 punching the workpiece. During the punching process, the punch head 2 moves downward towards the workpiece. A telescopic protective cover 4 is arranged between the worktable 1 and the mounting frame 3, and the telescopic protective cover 4 is fixed to a mounting plate 7. A pressure rod 5 is arranged on the drive cylinder of the punch head 2, and the end of the pressure rod 5 is located above the mounting plate 7. During the downward movement of the punch head 2, it drives the pressure rod 5 to apply pressure to the mounting plate 7, and the mounting plate 7 drives... The telescopic protective cover 4 moves downward to cover the press head 2 and the workpiece being processed, thus protecting the processing environment. The telescopic protective cover 4 is designed to be telescopic, and it hangs down naturally under its own weight. At this time, the telescopic protective cover 4 is at its maximum height. When the bottom of the telescopic protective cover 4 touches the worktable 1, it adapts to the height of the mounting plate 7 by telescopic adjustment. The telescopic protective cover 4 can be flexibly adjusted according to the different moving distances of the press head 2 and the height of the workpiece. The mounting plate 7 is connected to the mounting frame 3 by a spring 6. When the press head 2 moves upward, the spring 6 drives the mounting plate 7 and the telescopic protective cover 4 to move upward and remove them from around the workpiece being processed.

[0018] The telescopic protective cover 4 includes a first cover 4-1 and a second cover 4-2. The first cover 4-1 and the second cover 4-2 are slidably engaged, and the telescopic protective cover 4 is extended and retracted through the sliding engagement between the first cover 4-1 and the second cover 4-2.

[0019] The telescopic protective cover 4 is specifically designed as follows: the bottom end of the first cover 4-1 is located in the limiting groove 4-3 inside the second cover 4-2; the bottom end of the second cover 4-2 is provided with a limiting block 4-4; the top end of the second cover 4-2 is provided with a limiting plate 4-5; the limiting plate 4-5 is provided with a sliding groove 4-6; the side wall of the first cover 4-1 slides in conjunction with the sliding groove 4-6; the limiting block 4-4 can slide in the limiting groove 4-3; the limiting plate 4-5 restricts the limiting block 4-4 within the limiting groove 4-3; the movement of the second cover 4-2 within the first cover 4-1 realizes the telescopic structure of the telescopic protective cover 4.

[0020] Two sets of springs 6 are provided, respectively located on both sides of the mounting plate 7. Under the action of the pressure rod 5, the springs 6 are always in a stretched state, and the springs 6 always exert an upward pulling force on the mounting plate 7, causing the mounting plate 7 to move upward with the stamping head 2.

[0021] A machining groove 7-1 is provided in the middle of the mounting plate 7. The machining groove 7-1 is located directly below the stamping head 2. The stamping head 2 moves downward from the machining groove 7-1 to stamp the workpiece.

[0022] In this invention, the workpiece can be stamped by moving the press head 2, and the telescopic protective cover 4 can be moved to protect the workpiece from the surrounding area, thus effectively protecting the processing environment.
